hey Kozzy... welcome to the forum from up the north... when it comes to a topbox for your STeed you may also want to consider the fact that an oringal "Honda" topbox will not fit two full face helmets.... whereas an aftermarket topbox, such as a Givi 47 litre, will... the lid latch on the Honda Box can also be a concern as it is possible to unmount the topbox when accessing the lid, therefore losing the topbox when riding away... i have my Givi topbox bolted down through it's mounting plate (which comes with the Givi topbox) because it also is the backrest for the copilot, navigator, lollie supplier... pillion. cheers, John & Kate.
